I would like to get a box built for my 12 RE XXX (year 2008 I believe) Vehicle Make and Model: 2007 civic si coupe Direct of box/sub: rear firing Ported 1 sub 12'' RE XXX Max dimension: 40 (W) x 30 (Depth) x 17.5 (H) zipcode: 95122 (I can pick up in Gilroy) I would like to have it tuned to 4.0cubic ft @ 33hz, go low. If you have a better suggestion for the best tune, please feel free to let me know. The box should also have double baffle and flush mount.
